To aZZ whom it may concern:

Be it known that I, CLARENCE HARRER, a citizen of the United States, andresident .of Port Washington, in the county of Ozaukee and State of'Wisconsin, have invented certain new and useful Improvements inAutomatic Bottle Closures; and I do hereby declare that the following isa full, clear, and exact description thereof.

My invention relates to new and useful improvements in receptacleclosures, especially those which are adapted to be automatic in theirvoperation.

It is the principal object of this invention.

to provide a closure for such articles as syrup pitchers and liquidcontainers generally which will readily swing to open position when thereceptacle is tilted to empty the contents, and automaticallyreturn toclosed position when the receptacle is upright.

An additional object of the invention is to provide a closure of thischaracter in which springs and like operating means have beeneliminated.

A further object of the invention is to provide means for closingreceptacle covers which is so arranged that the force of theundischarged fluid in returning to its level in the receptacle willoperate to aid in shutting the closure.

With these general objects in view, the invention resides in thenovel'features of con-- struction, combination and arrangement of partswhich will be hereinafter more particularly described and claimed.

In the accompanying drawing,

Figure 1 represents a vertical sectional view taken substantially on theplane of the line 11 of Figure'2, and showing the preferred manner ofconstructing the invention, and

Figure 2 is a plane view of the structure as shown in Figure 1.

Referring more particularly to the drawing, it will be noted that thereference character 1 pertains to a receptacle or container of anydesired size orshape, having a spout attaching member 2 seated in itsneck. This attaching member consists of a receptacle engaging nozzle 3and an internal threaded spout receiving cup 4. A spout 5 is secured tothe attaching member 2 by a reduced and threaded end 6, the spoutengaging portion 4 of said member 2 being in contact with a flange 7 asis most clearly shown in Figure 1.

will act as a funnel.

This spouto has its upper openend pro- Vlded W1th a cover 8 which ishinged at one,

side as at 9. Depending from the cover 8.

adjacent the hinge thereof and disposed vertically and adjacent thehinged side of the spout wall.

en, however, the receptacle 1 and the spout? are tilted to discharge thecontents, the weight 11 will tend to drop toward the opposite wall ofthe spout from that which 1t is normally adjacent,thus swinging the tionof the hanger rod 10 and its weight 11 within the spout 5 is a hangerrod 10,. the same having a ball or any suitably shaped weight 11 on itslower free end. When the cover 8 is closed the hanger rod is disposed vsI is automatically closed by the swinging acas they return to theirposition of rest. Ob-

viously any liquid which tends to flow back into the containerfrom theopen end of the spout will strike against the weight ll and thus urge itlIltO' its normal inactive .position. Thls feature is particularlybeneficial in aiding the-weight to return the cover to closed positionwhen there is any tendency of the latter to stick.

It will. also be noted that the spout may be detached from the cup 4,owing to the threaded connection 6. This'is very convenient whenrefilling the bottle since the cup 4 It is not desirable to y p removethe neck portion 3 or the attaching portion 2 since the latter includesthe downwardly extending cork portion which forms a lining for the neckof the bottle and is comparatively thin and easily broken. From-theforegoing description taken in connection with the accompanying drawing,it will be appreciated that I have invented a very simply constructedautomatic closure which can be applied -to 7 various types ofreceptacles and containers, and ne which can be inexpensivelymanufactured in a great variety of shapes and styles. In I other words,various changes may be, made to formportions of the different parts ofthe invention without departing from the principles thereof orsacrificing any of. its advantages.

I claim:

A bottle closure comprising a'hollow neck engaging portion having itsupper end 4 flared to form- 'a comparatively wide mouth throetgh whichthe bottle may be filled, a spout detachably connected to said flaredend at the topmost portion of said flared 1 end, an annularr'i'b on saidspout adaptincree'sed in cross sectional area adjacent to 10 seed flaredend to provide space for sand gravity actuated means.

In testimonythat lrclainl the foregoing I have hereunto 'set my hand atPort Washington, vin the county of Ozaukee and State of 15 WVisconsin.
